As usual, apologies for any formatting issues due to extracting
message threads out of digests ...<br>
<br>
Anyhow., i have determined where everything goes terribly wrong with
OSX clients: OSX 10.10.3 ("out of the box" Yosemite) works fine
using <a href="http://linsec.ca" target="_blank">linsec.ca</a>'s guidance. However, the second you patch to
10.10.5 or upgrade to El Capitan (10.11.5), authentication fails
absolutely in the ways described in earlier threads. Colleagues who
i've spoken with who are trying to set up IPA at their facilities
report the same problem and it's a total show-stopper. Interesting
how all(?) of what is written on the topic of OSX and IPA dries up
after 10.8, although we've seen in an earlier thread reports of 10.9
working. I've repeated this test a few times and the result is
always the same. - 10.10.3 is the last OSX capable of authenticating
against IPA using currently available knowledge. <br>
<br>
Running tcpdump on 10.10.3 and a 10.10.5 clients show very different
authentication dialogues. I'm afraid, however, that i lack the
skills to interpret where exactly the later OSX release is failing.
I have my (unfounded) suspicions - that SASL binding for LDAP and
kerberos are implicated. 10.10.3 certainly shows no kerberos
transactions whereas 10.10.5<br>
<br>
Re DNS: both client types resolve all SRV records hosted in IPA
fine. I even went so far as setting up rudimentary ipv6 as there
were some AAAA requests that were going unanswered and it thought it
might related (not, as it turns out)<br>
<br>
So, would anyone on the IPA team be interested in looking at some
packet captures? I'm completely up for working with you, providing
whatever is needed and doing testing. It would be fantastic to
restore IPA-based auth for newer OSX releases.<br>
<br>
best regards,<br>

Hi,
Are you only having problems to login to login to OSX with the
IPA user
now? If that is the case then check the DNS settings you are
using and make
sure the IPA server is listed first and that it has full name.
Exactly the
same problem occurred for me with the slow logins to OSX which
was due to
the DNS settings and that OSX only used short name of IPA server
during
login (if I logged in as local user I could ping and lookup
hosts using
short name)

<pre>I had to configure /etc/krb5.conf, and to avoid the requested reboot, I
did a "dscacheutil -flushcache", both as the logged in user and as root.
I tried enabling the anonymous bind and now also the directory browser
(and all the login process) works as expected.

Thanks, John and Nicola
Kerberos occurred to me as well late in the day yesterday. Happily (?),
knit works fine simply specifying the user in question with no need to
suffix with the kerberos realm
I did find that my test user had an expired password, which i fixed on the
IPA server. This was never flagged up under Linux, btw. It has not change
anything, however, other than not prompting for password changes that never
take effect. Funnily, it expired in the midst of testing - fun.
I was mistaken when i said i was unable to log in - it turns out that it
takes almost 10 minutes for a login from the frintend to complete - i just
didn't wait long enough. 10 mins is of course unacceptable :) "su - user"
and "login user" fail outright after rejecting accept any user's password
DNS is fine and i can resolve ldap and kerberos SRV records from the Mac
In line with Nicola's experience, i can browse groups and users in the
Directory Editor and all attributes appear spot on.
Besides modding /etc/pam.d/authorization, adding a corrected
edu.mit.kerberos to /LibraryPreferences and setting up the directory per
<a href="http://linsec.ca" target="_blank">linsec.ca</a>, can anyone think of something i may have missed? It's a real
shame that the documentation on this stops around 5 years ago.
IPA devs: is there anything i should be on the lookout for in the dirsrv
or krb5 logs on the IPA master? I've disabled the secondary to prevent
replication from clouding the log events
thanks, everyone

Hello, I tried 2 weeks ago from Mavericks (OSX 10.9), but I had the
opposite problem: kinit works fine, while I'm unable to see users with
Directory Admin ((it always says it cant' connect, either with or without
SSL)
I disabled anonymous searches in 389-ds, by the way.

Hi Cal,
Does a kinit work from a terminal? Does it work if you use "kinit user" or
just if you use "kinit <a href="mailto:user@REALM.suffix" target="_blank"><user@REALM.suffix></a><a href="mailto:user@REALM.suffix" target="_blank">user@REALM.suffix</a>"

<pre>Hi, all
I'm attempting to set up LDAP auth (against IPA server 4.10) from a OSX
10.10.5 (Yosemite) client
Using the excellent instructions at

I've populated the specified files, d/l'd the cert, am able to configure
Users and Groups objects/attribs and browse both from within OSX's
Directory Utility. ldapsearch similarly returns the expected results.
In spite of this, i'm unable to authenticate as any IPA-LDAP user on this
system
dirsrv log on the ipa master shows no apparent errors - remote auth
attempts exit with "RESULT err=0 tag=101 nentries=1 etime=0", but tell the
truth, there so much stuff there and being rather inexperienced with LDAP
diags i might easily be missing something in the details
The <a href="http://linsec.ca" target="_blank">linsec.ca</a> instructions were written in the 10.7-10.8 era so
something may have changed since. Having said that, we've had no problems
authenticating against our existing OpenLDAP server (which IPA is slated to
replace) right up to 10.10.5 with no zero to our Directory Utility setup.
Hoping someone here has some contemporary experience with OSX and IPA and
for whom this issue rings a bell?
many thanks
